Ultra-low volume aerosol are specially designed for agricultural drones, which has the following characteristics:
1.The quantity of spray is low and the working efficiency is high.
For example, conventional pesticides are applied 30-50L per mu while ultra-low volume aerosol uses 500ML or so per mu.

2.The concentration is high. The concentration of ultra low-volume spray is usually 25-50%, hundreds of times higher than that of conventional spray.
3.The mist is thin. The droplet diameter of ultra-low volume sprays is generally in the range of 70-100 microns, smaller than that of conventional sprays (200-300 microns).
In the below pictures, the upper part is the fog droplet from the fan-shaped nozzle of agricultural drone while the lower part is the fog droplet from the artificial medicine box.

4.Oil carrier. The oil carrier with high boiling point is mainly used in ultra-low volume spray, which has low volatility and good dispersity, while water is mainly used as carrier in conventional spray.
In below pictures, at the left side, water mist accumulation as water droplets with poor dispersion by agricultural drone spraying with Water.
The right picture shows the sprayed clear water with special auxiliary for flight prevention by agricultural drone. The water mist on the leaf surface is dispersed, which is more favorable for absorption.

Agricultural drone not only improves the efficiency of plant protection, but also reduces the pesticide use and water consumption, which is in line with the development plan of green agriculture in China and improves our food safety.
